It’s long been known that all around health is the result of exercising good mental, physical and spiritual habits. Abuse or just lack of use of any one of these is likely to cause decline in all three. Along comes a study that shows that laboratory mice who have exercise wheels in their cages actually show an increase in new neurons compared to their couch-potato counterparts. Using something called the Morris water maze, the rodent equivalent of an IQ test, it was noted that the mice who exercised showed new growth of neurons, the brain cells that allow us to think. An article in the New York Times Play Magazine reveals that human brains can do the same thing. In fact, scientists have been finding more evidence that the human brain is not only capable of renewing itself, but that exercise speeds the process. The same can be said for stretching your brain with mental exercises. If a 3 ounce mouse can build new neurons, imagine what you can do for yourself with just a little exercise.
